Analysis On The Inspection And Supervision Management System Of Railway Enterprise Based On Stochastic Petri Net

With the rapid development of the national economy, the scope of enterprise business become extension and the wide of enterprises scale increasing, proposed new requirements to the enterprise inspection and supervision of the work. And in order to promote the railway construction and operation of a healthy and sustainable development, after the separation of government and enterprises, the railway enterprises go on accelerating railway investment and financing system reform and price reform, hope to be able to reduce the cost, improve efficiency.so it is paid more and more attention. So we should focus on the development of railway inspection and supervision management system, improve office efficiency, to make a contribution to the final enterprise benefit. So this paper of process research to railway inspection and supervision management system has practical significance, reference for practical work. The main research contents are as follows:(1) Make a introduce in detail of railway inspection and supervision main contents, including Including the development situation, the joint inspection supervision system of work, what we had achievements nowadays, and basic requirements to the inspection personnel in the work, and describes the working to carry out some of the problems found in the process of: lack of work enthusiasm, initiative and creative; professional department did not play its functions; low quality of matters feedback. And puts forward the corresponding solutions: improve step by step review system, focus on strengthening the on-site inspection work supervision, establish a comprehensive and perfect inspection supervision system, strengthen inspection and supervision of the work of professional..(2) Introduced the basic theory of Petri network in detail, including its basic terms, origin and development, definition, basic behavior, nature, characteristics, and so on. Then introduced the basic theory and definition of stochastic Petri net.(3) Through the process analysis of railway inspection and supervision of the work, construct a Petri net model of the railway inspection supervision management system, and verify the correctness of the model.(4) Based on the theory of reachable tree, Markov chain, steady state probability equation and performance index, make a performance analysis of the constructed model. Through the construction of the reachability graph, the construction of the Markov chain, the calculation of the stable probability, the calculation of the performance index, Through the calculation results of the busy probability, idle probability and transition utilization, make out what will be busy in the system and what will be easy to produce information accumulation and in favor to the utilization of personnel?material in the system, reference for practical work.
